Application filed May 19, 1905- Serial No 261,I46.

- Delaware, have invented a new and useful Improvement in Machines for Making Tubes from Pulp, Paper, or Similar Material, of which the following is a full, clear, and exact description, reference bein had to the accompanying drawings, which orm a partof this specification.

supports T and T.

The object of'my invention is the production of a machine in which a lurality of mandrels or winders may be use u on which successively rolls or tubes may e wound and also to remove said rolls or tubes without removin the mandrels from the machine.

I.wi l first describe the embodiment of my invention illustrated in the accompanying drawin s and then point out the invention in the c aims.

In the drawings, Figure l is a side or end elevation of the machine. Fig. 2 is an end view of a portion of Fi 3 from the line 2 2 looking to the right. ig. 3 is a front elevation of the entire machine. Fig. 4 is a view, partially in section, of a portion of the machine. Fig. 5 is a longitudinal section of another portion of the machine. 1

A is the frame of the machine, made up in the usual manner of a tub and housings, the latter forming the side walls of the tub.

B is the mold-roll-rotating in the tub and su ported in the housings. C is the couchrofi supported in the housings of the machine and contacting with the mold-roll. These rolls are driven by the gearing B B B B and pulley D on shaft E.

H is a shaft supported in the bearin s N N, mounted on the housings bf the mac ine. Upon this shaft are mounted the spiders or These spiders or supports support between them a pluralit of winding-rolls or mandrels, each on a sha 't X. Four winding-rolls are shown in the drawings equispaced around these spiders. As the construction of the spiders or supports for each winding-roll is t esame, it is only necessary to'describe one. The support T, which I term the pivot-sup ort, is provided with a groove or slot T or each winding-roll, in which rests a slide-block Y, free to move therein. Through this block passes the end of shaft X of a winding-roll, such end being made square or rectangular. The block is formed with a pivot K, which passes through an orifice in the shaft. Beyond the groove is the guide U, in which the end of the shaft rests. On the support T is the ring 0 which prevents the shaft X at this end from disengagin with the spider. The support T is provi ed with guides U foreachwinding-roll shaft similar to the guides U of the support T. Adjacent to each guide U bymeans of the pin A is secured the latch B, which engages with the shaft in the guide U and by means of the spring C locks the shaft from moving in the guide. Each guide U and U has a pocket inwhich apinW, acted on by spring V, rests, the pins under the action of the spring tending to move outward radially, thus contacting with the windingroll shafts.

, On the driving-shaft E is the eccentric F,- connected, by means of the eccentric-rod I and the pin J, to the crank G, mounted loosely upon the shaft H. On the end of crank G a pin K connects the crank with a pawl L, which pawl is adapted to operate the ratchetdisk M, securely keyed to the shaft H. This pawl is provided with a in J, which in certain portionsof acam R 1s adapted to be acted on by the cam and the pawl lifted freefrom the ratchet-disk. The cam R is carried by the boss formed with or connected to the crank-arm O. A spiral spring Q loosely surrounds the shaft H and atone end is connected with the bearing of the shaft and the other end to the crank-arm O. The tendency of this spring is to move the cam R out of line of pin J on pawl L and allow the pawl to 0 .erate the ratchet-disk, and thus move the sfiaft H and turn the sup ort's, bringing successively the winding-r0 ls in operative relation to the couch-roll. movement normally takin place and to allow it only to take place w en a iven winding-roll has received the re uire number of layers of pulp and then al ow it tooperate only sufficiently to move the full mandrel away and another mandrel into position, I provide the following mechanism.

The crank-arm O at its free end is slotted and carries an adjustable pin S. This pin is in line with the squared end of the windingroll shaft when the winding-roll is free from In order to prevent this vertically unti pulp and in erative relation with the couchroller, and t erefore holds the crank against the action of the spring and the ,ratchetdisk in action, and no movement of the shaft occurs. As, however, the winding-roll has layers of pulp placed upon it, its shaft moves it has passed above the pin S, when the pin is released and the cam-disk moved out of action, and the shaftis moved, which causes the winding roll ust referred to to move away from the couch-roll and the next succeedingwinder to approach it. In the movement of the last-mentioned roll its shaft end will strike the pin S on the crank arm 0 and move arm against the spring, moving the cam R again into action, stopping the movement of the shaft, and through the medium of the that position.

In order to cause the winding-rolls to stop with certainty in the ro er position with respect to the couch-r0 I, employ the following mechanism: Fastened to the housing of pin Slocking the arm in themachine is the recess-bracket D, carry- 25 ing the adjustable stop I, which stop is in line with the end of the shaft of the winding- ,roll andis adjustable, so as to be above the bottom of the shaft until the desired number of layers of pulp have been wound thereon. E is a spring-latch. As the empty Windingroll approaches the roper position with respect to the couch-r0 ler its shaft, as before described, operates the crank-arm 0. It also depresses and passes beyond the latch E, which rises behind it. The forward movement of the windin -roll is stopped by striking the stop I. T e movement of the winding-roll in one direction is thus stopped, and its position is correctly determined by being held between the stop I and latch E. When the winding-roll is covered with layers of pul to the determined extent and its shaft is lifted above the stop I and pin S, it is free to move under the action of the pawl and ratchet.

As may be seen from the 'hereinbefore description, the winding rolls are successively and automatically brought into and when covered the desired extentremoved from operative position. The winding-roll covered with pulp moves into the position denotedby P, Fig. 2, and the tube may be stripped therefrom without removing the windlng-roll inthe following manner: The latch is moved from the shaft and the Wind ing-roll turned on its pivotal connection with blockY, so that the end in support T will move free from the support, and the tube may be stripped there om. The windingroll is then swung back and the latch brought again into holding osition.

By my improved machine as the windingrolls do not have to be removed from the machine to clear the tube therefrom I have with the plurality of winding rolls I use practically a continuous operation.

Having now full described my invention, what I claim, and esire to protect by Letters Patent, is
